Method Detail

getName

public String getName()

Deprecated.

Description copied from interface: AuthScheme

Returns textual designation of the given authentication scheme.

Specified by:

getName in interface AuthScheme

Returns:

the name of the given authentication scheme

isConnectionBased

public boolean isConnectionBased()

Deprecated.

Description copied from interface: AuthScheme

Determines if the authentication scheme is expected to provide an authorization response on a per connection basis instead of the standard per request basis

Specified by:

isConnectionBased in interface AuthScheme

Returns:

true if the scheme is connection based, false if the scheme is request based.

getRealm

public String getRealm()

Deprecated.

Description copied from interface: AuthScheme

Returns authentication realm. If the concept of an authentication realm is not applicable to the given authentication scheme, returns null.

Specified by:

getRealm in interface AuthScheme

Returns:

the authentication realm

processChallenge

public void processChallenge(AuthChallenge authChallenge,
                             org.apache.hc.core5.http.protocol.HttpContext context)
                      throws MalformedChallengeException

Deprecated.

Description copied from interface: AuthScheme

Processes the given auth challenge. Some authentication schemes may involve multiple challenge-response exchanges. Such schemes must be able to maintain internal state when dealing with sequential challenges

Please note auth schemes that perform mutual authentication must implement AuthScheme.processChallenge(HttpHost, boolean, AuthChallenge, HttpContext) and AuthScheme.isChallengeExpected() instead.

Specified by:

processChallenge in interface AuthScheme

Parameters:

authChallenge - the auth challenge

context - HTTP context

Throws:

MalformedChallengeException - in case the auth challenge is incomplete, malformed or otherwise invalid.

See Also:

AuthScheme.processChallenge(HttpHost, boolean, AuthChallenge, HttpContext)

isResponseReady

public boolean isResponseReady(org.apache.hc.core5.http.HttpHost host,
                               CredentialsProvider credentialsProvider,
                               org.apache.hc.core5.http.protocol.HttpContext context)
                        throws AuthenticationException

Deprecated.

Description copied from interface: AuthScheme

Determines whether or not an authorization response can be generated based on the actual authentication state. Generally the outcome of this method will depend upon availability of user credentials necessary to produce an authorization response.

Specified by:

isResponseReady in interface AuthScheme

credentialsProvider - The credentials to be used for authentication

context - HTTP context

Returns:

true if an authorization response can be generated and the authentication handshake can proceed, false otherwise.

Throws:

AuthenticationException - if authorization string cannot be generated due to an authentication failure

getPrincipal

public Principal getPrincipal()

Deprecated.

Description copied from interface: AuthScheme

Returns Principal whose credentials are used to generate an authentication response. Connection based schemes are required to return a user Principal if authorization applies to for the entire life span of connection.

Specified by:

getPrincipal in interface AuthScheme

Returns:

user principal

AuthScheme.isConnectionBased()

generateAuthResponse

public String generateAuthResponse(org.apache.hc.core5.http.HttpHost host,
                                   org.apache.hc.core5.http.HttpRequest request,
                                   org.apache.hc.core5.http.protocol.HttpContext context)
                            throws AuthenticationException

Deprecated.

Description copied from interface: AuthScheme

Generates an authorization response based on the current state. Some authentication schemes may need to load user credentials required to generate an authorization response from a CredentialsProvider prior to this method call.

Specified by:

generateAuthResponse in interface AuthScheme

request - The request being authenticated

context - HTTP context

Returns:

authorization header

Throws:

AuthenticationException - if authorization string cannot be generated due to an authentication failure

See Also:

AuthScheme.isResponseReady(HttpHost, CredentialsProvider, HttpContext)

isChallengeComplete

public boolean isChallengeComplete()

Deprecated.

Description copied from interface: AuthScheme

Authentication process may involve a series of challenge-response exchanges. This method tests if the authorization process has been fully completed (either successfully or unsuccessfully), that is, all the required authorization challenges have been processed in their entirety.

Please note if the scheme returns true from this method in response to a challenge, it effectively implies a failure to respond to this challenge and termination of the authentication process.

Specified by:

isChallengeComplete in interface AuthScheme

Returns:

true if the authentication process has been completed, false otherwise.

toString

public String toString()

Deprecated.

Overrides:

toString in class Object
